My car usually takes around 8 miles in these lower temperatures, 30-40mph roads, to reach full operating temperature on the oil temp gauge.

If you use the coolant temp display in the OBC hidden menu you can see when the thermostat opens : typically the coolant temp will increase reasonably quickly to 70-80C then either stop increasing, or may decrease, for a while when the stat opens and the coolant from the radiator starts to flow around the block. Once all coolant has reached the same temperature the reading will increase again, up to full operating temp. This seems to be 98-108C for my car, depending on how hard the engine is working.
